Title: Load cell mounting and alignment for weighing means
IPC: G01G19/04
Filed: 1963-01-29
Abstract: 1,017,361. Weighing apparatus. ATLAS BOLT & SCREW CO. Jan. 29, 1963 [Feb. 23, 1962], No. 3563/63. Headings G1N and G1W. The load (e.g. railway vehicles) on a weighbridge is measured by means of a plurality of load cells which may be electric strain gauges. To prevent horizontal load on the load cells the weighbridge rests on a stabilizing frame 2 (Fig. 3) which comprises longitudinal check bars 20 and lateral check bars 21 supported at their middles on a base 4 by supports 22, 23 and welded at their ends to corner plates 24. A load cell assembly 3 (Fig. 4) is interposed between each corner plate and the base 4 and comprises a load cell 30 in a housing 31 which is welded to the bottom of a corner plate 24. A stem 33 of each load cell has a convex top surface and seats in a socket 39 of the respective corner plate while the bottom of the cell rests on a steel ball. This is to prevent horizontal loading of the cell which might result from changes in the length of the check bars due to temperature variations. The housings 31 are spaced from the base 4 and are lined with thermal insulation 56, 57, which may be fibreglass. The check bars 20, 21 are of such a thickness that their own weight over the length of their span will cause a downward deflection at their ends in excess of the vertical movement of the load cells and thus the bars will offer no resistance to the load such as would affect the load measurement.

Abstract: 865,937. Regulating road vehicle height. FABBRICA ITALIANA MAGNETI MARELLI S.p.A. Feb. 3, 1959 [Feb. 12, 1958], No. 3757/59. Class 108(2). The inlet and exhaust valves Vi, Vs, of a road vehicle pneumatic suspension height control valve assembly are adapted to be lifted by respective push rods 3, 3<SP>1</SP> which are operable by a cup-shaped member 16 connected by a lever 15 to the vehicle axle. The edge of the element 16 is divided into two axially staggered sections each extending over approximately a semi-circumference. In the normal position of the suspension, the push rods 3, 3<SP>1</SP>, engage the edge section Ps of the element 16 which is furthest from the valves Vi, Vs. Thus on rotation of the lever 15 from the position shown in either direction, the ends of one or other of the push rods 3, 3<SP>1</SP> is engaged by the other edge section Pi of the element 16 so as to deflect the push rod and thus lift the associated valves Vi, or Vs. When the valve Vi is lifted air can pass from a reservoir (not shown) through conduit connection 4 and the valve Vi to a passage 7, lifting a non-return valve Vr and passing via a port 13 to a conduit connection 4<SP>1</SP> leading to the pneumatic spring (not shown). When the valve Vs is lifted, air passes from the pneumatic spring through conduit connection 4<SP>1</SP>, valve Vs and passage 7<SP>1</SP> to atmosphere.

IPC: G01F11/02
Filed: 1928-02-09
Abstract: 307,186. Andrew, N. P., and Macfie, W. L. Feb. 9, 1928. Lever-actuated pumps; full-stroke devices; oscillating-cylinder pumps. - In an oscillating cylinder pump for delivering measured quantities of liquids a device is attached to the actuating lever to ensure that it completes its full stroke before reversal. A controlling lever F, pivoted to a fixed frame D on the supply tank, is recessed to receive the locking member G. The actuating lever C carries a pin to which is attached a double-ended pawl C3 and a guide roller C2. When the actuating lever is moving outward towards stop El, reversed motion is prevented by the pawl being engaged in the rack G4 by the spring C5. At the end of the stroke the locking member G is lifted by its spring G2, thereby removing the rack from the pawl so that reversal can then take place. Similarly, reversal on the inward stroke is prevented by the pawl engaging with rack G5. On the suction stroke the cranked lever B3 engages with the stop El and actuates the piston through link B2, the cylinder bottom then registering with the port D1 in the supply tank. Similarly the exhaust stroke is performed by lever B3 engaging with stop E2.

Title: Improvements in or relating to television and like apparatus
IPC: H04N5/74
Filed: 1936-02-13
Abstract: 470,347. Television. BAIRD TELEVISION, Ltd., and BAIRD, J. L. Feb. 13, 1936, No. 4332. [Classes 39 (i) and 40 (iii)] Scanning-apparatus for a television or like transmitter or receiver comprises an array of electro-optical cells containing a medium adapted to become effectively dichroic when stressed by an electrical or magnetic field. The array of cells may consist of a pair of parallel glass plates between which is a colloidal suspension of crystals such as herapathite, which under their action of an electric field tend to become oriented so as to occult polarized light passing through the medium. As shown in section in Figs. 1 and 2a, thin metal strips 2 connected together may be arranged between the plates 25, 26, a number of small elemental electrodes 3 being arranged between these strips, each having a minute button 4 passing through the plate 25. In the receiver shown in Fig. 2, light from a source 11 is plane polarized at 14 and passes to the screen 17 through the array of cells 6 mounted in a cathode-ray tube. The electron beam 10, modulated by the television signals, traverses the array, the potential of each electrode 3 being varied in turn with respect to the strip on either side of it, so as to change the amount of light passing through that cell. The leakage is such that each electrode 3 discharges in about <1>/16 of a second. The array 6 may be made integral with the end wall of the cathode ray tube, the electrodes 3 passing through the tube to buttons 4 within the tube. Alternatively, the array of cells may be made by sputtering metallic particles on a sheet of glass or mica, the colloidal suspension of crystals being between this sheet and another sheet with a continuous and translucent metallic film. In a further modification, Fig. 3 (not shown) a polished metal plate at the back of the array of cells reflects light through the dichroic material to the viewing screen. Methods of preparing dichroic crystals are described in Specifications 412,179 and 433,455, [both in Group XX]. The crystals may be suspended in cellulose nitrate or in Canada balsam kept fluid by heat. A line array of cells activated in turn by magnets controlled by the commutator described in Specification 347,741 may be used, the other component of scanning being, e.g. a mirror drum. Specification 454,589 also is referred to.
